as particularly shy. In fact he was more easily approached than the crowned sparrows which were present in flocks and more approach- able (by a hundred yards or over) than the phainopeplas (seen one at a time). Still later, while we were stealing up on another (?) thr asher a quarter mile west of the first one seen, and were in plain sight in the open, still another thrasher flew from some dist- ance away directly toward us, passed a few feet over our heads, and went down in the barranca and began to dig just like Brownie. This one seemed to pay no attention to us, moving about freely in search of food. These two birds were in sight at the same time. We found many old nests, perhaps 8, but nothing we could pos- itively identify as new ones or nests in the course of construction. There were two nests consisting of foundation twigs only which may or may not have been new and may or may not have been thrasher nests. Our only original contribution to ornithology consisted of a cottonwood tree containing 3 hawk's nest, a mockingbird, another small nest and a veritable wild-cat dozing in one of the hawk nest. This wild-cat was the tamest "bird" of the day. We bombarded him at a range of about 20 feet with pieces of bark, soft lumps of earth and "buffalo chips" scoring frequently for about a half an hour, without causing him to leave the tree. The most he would do was to rumble and growl, occasionally move out of the nest, then go back to it again and blink at us sleepily. We acknowledged our defeat and left him in possession of the field. A half hour or so after- ward, our wanderings brought us again near the tree. He was still in the nest. A broadside by Dr. Reynolds, the first of the second engagement, caused him to become bored with the whole affair. He descended with considerable dignity and galloped off in a wide arc through the atriplex, of which we appeared to be the center. He was spotted by a raven, who circled about him and repeatedly swooped down upon him, following him for a hundred yards or so.
